通过水热的方法合成得到2个由萘氧乙酸及眯唑配体构筑的配合物Zn(2-naph)2(imi)2和2Cu(2-naph)2(imi)2(H2O)·Cu(2-naph)2(imi)2(H2O)(2)(2-naph=2-naphthoxyacetate, imi=imidazole),它们的结构通过X射线晶体衍射、红外光谱和元素分析得到确定.在配合物1中,锌原子与来自不同2-萘氧乙酸配体中的2个羧酸氧原子和不同的咪唑分子中的2个氮原子形成了变形的四面体的几何构型.单个分子通过N-H…O氧键连接形成了一维链,然后在C-H…π弱作用下形成了变形的四面体的几何构型.配合物2有2个独立的铜中心.它们有几乎相同的配位环境.每个铜中心都是变形的四方锥的配位构型.来自不同的2-萘氧乙酸配体中的2个羧酸氧原子和不同的咪唑分子中的2个氮原子形成了一个相对规则的四方锥赤道平面,配位水分子位于平面上方.配合物2的分子通过N-H…O和O-H…O氢键连接形成了二维结构.2个配合物的热稳定和固体荧光性质在本文中也得到了研究和讨论.

Two complexes assembled by 2-naphthoxyacetate and imidazole ligands, Zn(2-naph)2(imi)2 (1) and 2Cu(2-naph)2(imi)2(H2O)·Cu(2-naph)2(imi)2(H2O) (2) (where 2-naph=2-naphthoxyacetate and imi=imidazole) have been hydrothermally synthesized, and their structures have been determined by X-ray diffraction. In complex 1, Zn(Ⅱ) is in a distorted tetrahedron environment with two carboxylate oxygen atoms from two 2-naphthoxyacetate ligands and two nitrogen atoms from two imidazole ligands. The single molecules of complex 1 are linked by N-H…O hydrogen bonds to generate a one-dimensional chain, then further form a three-dimensional structure by the C-H…πweak interactions. Complex 2 has two independent Cu(Ⅱ) centers with the same coordination environment. Each Cu(Ⅱ) center is in a distorted tetragonal pyramid coordination geometry. Two carboxylate oxygen atoms from two 2-naphthoxyacetate ligands and two nitrogen atoms from two imidazole ligands form a relatively normal square plane of the tetragonal pyramid, and the water molecule occupies the apical position. Molecules of complex 2 are linked by N-H…O and O-H…O hydrogen bonds to yield a two-dimensional structure. The TGA and Luminescence properties in solid state of two complexes have been further studied and discussed. CCDC: 669291,1;669290,2.pical po
